Migos and Rich the Kid team up for the fourth installment in their Streets on Lock mixtape series. Once again, the Quality Control artists assemble a who’s who of trap hitmakers including Zaytoven, Murda Beatz, Sonny Digital, and Dun Deal. Rae Sremmurd, ILoveMakonnen, Peewee Longway, and Young Dolph pop up on the 27 tracks, while 2 Chainz and Jeezy join Migos on the remix to “Pipe It Up.”

Migos is also gearing up to release Migo Thuggin, its collaborative mixtape with Young Thug, on Halloween.
